Convert a file to LGR

To convert other file formats to the "PCB Fabrication Data" file type, you need software like KiCad or a similar tool.


About LGR files

The .LGR file extension primarily represents a Gerber PCB Layer file used in printed circuit board (PCB) fabrication. It defines the electrical connections, copper traces, and vias for a specific layer of a circuit board. Alternatively, .LGR functions as an optimization solver report file generated by software like LINDO or GLPK, or a session log from remote data loggers. Opening an .LGR file requires specialized Electronic Design Automation (EDA) software like KiCad or a dedicated Gerber Viewer. If the file is a text-based solver log, you can open it with standard code editors. Users face significant challenges with .LGR files. They are highly specialized and lack native support in web browsers, mobile devices, and standard office suites. A client or manufacturer without engineering tools cannot view your PCB designs. Solver logs can be massive, difficult to parse, and tedious to share with non-technical stakeholders. To solve these compatibility issues, you must convert the file. For sharing PCB designs visually, convert .LGR to PDF or PNG. For extracting data from solver reports, convert to CSV or TXT. Just drag and drop your file here to analyze and convert it - free, online, and without installing software.

Convert.Guru analyzes your LGR file, detects the exact format, and lets you read the text inside.

Users also converted GER, GRX and DRD files.


FAQ

If you want to convert LGR file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use KiCad or similar software from the "PCB Layout & Solver Logs" category. In the File menu, look for Save As… or Export….

To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to LGR, try KiCad or another comparable tool in the "PCB Layout & Solver Logs" category.



The LGR Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our LGR converter.
